Notes
  1. When ordering, please specify termination and packaging codes: e.g. DO1813H-473MLD
  2. Inductance tested at 100 kHz, 0.25 Vrms using an Agilent/HP 4263B LCR meter or equivalent.
  3. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  4. Isat: DC current at which the inductance drops 30% (typ) from its value without current.
    Temperature derating curves
  5. Irms: Current that causes a 40°C temperature rise from 25°C ambient.This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves

Termination:

  • L = RoHS compliant tin-silver (96.5/3.5) over copper.
  • = RoHS tin-silver-copper (95.5/4/0.5) over copper. (Special order, added cost)
  • S = non-RoHS tin-lead (63/37) over copper. (Special order, added cost)

Packaging:

  • 13" reel, machine-ready 
    EIA-481 embossed plastic tape (1000 parts per full reel).
  • B = Less than full reel 
    In tape, not machine ready.  To have a leader and trailer added ($25 charge), use code letter D instead.
